Somehow we have lost track of the fact that the MOST basic nature of sports is forcing the other team to react when they are NOT prepared to react, when they have NOT cinched up their batting gloves nice and tight and got into just the right position in the batter’s box and cleared their mind and thought through what the pitcher is likely to throw.
That may be the basic nature of football or basketball, but not baseball (in fact, not a lot of competitive sport). The battle between hitter and pitcher isn't who can react fastest. (In this scenario, the advantage goes completely to the pitcher who would then control every aspect of the at-bat, which would make the problems of poor hitting multiply even more.) The battle is a chess match, it's the pitcher who can throw one of a number of pitches, at a varying number of speeds and locations vs the hitter who's job is to figure it out. You can't rush that. You can't put a timer on it. You can't change the balance of power that allows the hitter to step up and mess up the timing/routine of the pitcher.
